The JBL Tune 230NC TWS can feel itchy and JBL’s product photography shows them sitting at a rather extreme angle in the ears, which is pretty uncomfortable—the ear tips don’t conform to the shape of my ear well. Turning the right earbud down toward the shoulder is a little more comfortable for me. However, this lessens the effectiveness of the seal and makes the bud slowly slide out of my ear a bit—it doesn’t fall out, but the isolation takes a hit. Chewing, smiling, and other facial movements also tend to move that bud around as a result. If you don’t struggle getting earbuds to stay in your ears, this may not apply.
The JBL Tune 230NC charging case holds the earbuds pretty securely, but opening the case will cause it to tip backward if you set it down on its narrow end. The case is necessary for charging the earbuds themselves—so don’t lose it. If you drop it, the lid will open and send the buds flying in random directions, too.
Both the case and the buds themselves have small “L” and “R” markings on them. Unfortunately, each is a raised, black letter on a black background. That might be difficult to see for people with impaired vision. It would be better to have different colors, textures, or shapes indicating each side, instead. Helpfully, the buds only fit properly in one orientation in the case.
